Jennifer Lawrence says working with Josh Hutcherson is like having a "dog licking your face".

The pair appear in the hotly-anticipated new movie The Hunger Games. Jennifer and Josh hit it off straight away and the actress claims her co-star is easy to like.

"We had tons of chemistry," Jennifer told MTV News. "He's charming and nice and sweet, like a dog licking your face."

Josh was unsure what to make of Jennifer's compliment. However, he revealed that they often puzzle people with their unique brand of humour when they are together.

"Like a dog licking your face, but 'Oh, God, get this away,'" he joked. "No, it's hard to get things done when we're together. I'm amazed this interview we've gotten as many questions in as we have. We just start going and end up talking about the most random things."

Josh, 19, plays Peeta in The Hunger Games. The post-apocalyptic drama takes place in a North American country where children are chosen to fight to the death. Josh's character has secretly been in love with Katniss played by Jennifer since they were children.

He loved working with Jennifer, 21, and hopes their bond resonates with fans when they see the movie.

"They had hired Jennifer, and they were trying to find Peeta. I had gone in for the first round of auditions, and a few weeks later, they brought me back," he revealed. "We did a chemistry read and kind of hit it off right away, I felt, for the second time, third time."
